Christian started his professional life as a researcher at Philips Research, driven by scientific exception within a unique team under the mentorship of now Prof Hermann Ney. Over time, he got more and more interested in how research can impact business. In 1993 he presented the first worldwide continuous speech recognition product for radiologists, insisting on continuous speech at a time when speaking to a machine was expected to be done with pauses --- between --- words.
From there on he got passionate about business and built up from scratch Nuance Communications in Europe, now the world leader of Speech Recognition. Seeing that speech recognition alone could not make it, he decided in 2001 to go up the value chain in order to industrialise the development of speech based services with VoiceObjects (now Aspect).A few years ago he went back into the research world to practice again on the technology side working in Karlsruhe with Prof Waibel on Speech Translation, at the German Research Center for Artificial Intelligence with Prof Josef van Genabith on Machine Translation and since a few months at RWTH Aachen on Information Extraction and Knowledge Base Population with Prof Hermann Ney
